Product details
Overview
MAX4066CSD+ from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch optimized for low-voltage operation from +2.0V to +16V, featuring 45Ω on-resistance at 12V, 2Ω channel-to-channel matching (MAX4066A variant), and 0.5µW quiescent power consumption. It serves as a bilateral signal routing device in battery-powered instrumentation and audio path switching.
For engineers reviewing the MAX4066CSD+ datasheet, MAX4066CSD+ pinout, MAX4066CSD+ application, or MAX4066CSD+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), low off-leakage (100pA for MAX4066A), TTL/CMOS-compatible control inputs, -86dB crosstalk, and support for rail-to-rail analog signal handling up to V+.
Technical Context
The MAX4066CSD+ implements four independent SPST switches using complementary MOSFET pairs per channel, enabling bidirectional analog signal flow with matched RON across all channels. Its architecture supports single-supply operation without negative rails, and internal ESD protection exceeds 2000V per Method 3015.7.
Switching is controlled by four logic inputs (IN1–IN4) compatible with TTL and CMOS voltage thresholds, directly enabling or disabling each COM–NO path. The device maintains signal integrity via low charge injection (≤10pC), wide bandwidth (>100MHz), and minimal distortion (0.03% THD).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 45Ω max at V+ = 12V - ensures minimal signal attenuation and voltage drop in precision signal paths |
| Channel Matching (∆RON) | 2Ω max (MAX4066A) - enables accurate gain/offset matching in multi-channel data acquisition |
| Off-Leakage Current | 100pA max at +25°C - preserves accuracy in high-impedance sample-and-hold and sensor interfaces |
| Supply Range | +2.0V to +16V - supports direct integration into 3V, 5V, and 12V systems without level-shifting |
| Bandwidth | >100MHz - suitable for video routing and fast data-acquisition front-ends |
| Crosstalk | -86dB - prevents interference between adjacent switched channels in dense layouts |
| THD | 0.03% - meets fidelity requirements for low-distortion audio signal routing |
Pinout & Package
MAX4066CSD+ is housed in a 14-pin narrow SO (Small Outline) package with standard JEDEC MS-012AC dimensions (5.00mm × 6.20mm × 1.75mm), RoHS-compliant and Pb-free.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 13 | NO1–NO4 (Normally Open) | Bidirectional analog output terminals; open-circuit when switch is OFF, connected to COM when ON |
| 2, 5, 10, 12 | COM1–COM4 (Common) | Bidirectional analog input terminals; shared node for each SPST switch path |
| 6, 7, 12, 14 | IN1–IN4 (Control Inputs) | TTL/CMOS-compatible digital inputs; HIGH enables corresponding switch, LOW disables it |
| 8 | GND | Analog and digital ground reference; must be low-impedance for leakage and noise control |
| 14 | V+ | Positive supply rail; powers analog switch core and logic interface; supports 2.0V–16V range |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4066 | Enables drop-in replacement in legacy designs without PCB revision |
| Guaranteed RON flatness | ≤6Ω over full signal range - maintains consistent gain and linearity across input voltage swing |
| Low charge injection | ≤10pC - minimizes voltage glitch in sample-and-hold and multiplexed ADC applications |
| V+ to GND signal handling | Rail-to-rail analog capability - eliminates need for external biasing in unipolar signal chains |
| ESD robustness | >2000V HBM - enhances reliability in manufacturing and end-equipment handling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066ACSD+ | Same pinout and electrical specs; rated for 0°C to +70°C (identical temp grade) | No functional difference; identical qualification and performance | Select MAX4066ACSD+ only if ordering under the "A" variant part number prefix per BOM requirement |
| ADG1414BRUZ | Quad SPST, 1.5Ω RON, ±15V dual-supply capable; higher cost, larger 16-lead TSSOP package | Better RON and wider voltage range but requires dual supplies and layout change | Choose ADG1414BRUZ only when sub-2Ω matching or bipolar supply operation is mandatory |

FAQ
What is the operating temperature range for MAX4066CSD+?
The MAX4066CSD+ is specified for operation from 0°C to +70°C. This commercial-grade temperature range is confirmed in the Ordering Information table and applies to both the MAX4066 and MAX4066A variants in the 14-pin narrow SO package. The 'C' suffix explicitly denotes this 0°C to +70°C rating, and thermal performance parameters (e.g., leakage, RON) are fully characterized across this span.
Does MAX4066CSD+ support rail-to-rail analog signal switching?
Yes, MAX4066CSD+ supports rail-to-rail analog signal switching: its analog signal range is specified as 0V to V+, meaning signals from ground up to the positive supply rail can pass through the switch without clipping or degradation. This is enabled by its CMOS transmission-gate architecture and is validated across V+ = 2.0V to 16V, including at 3V and 5V operation.
Is MAX4066CSD+ pin-compatible with the 74HC4066?
Yes, MAX4066CSD+ is explicitly pin-compatible with the industry-standard 74HC4066, as stated in the Features section of the datasheet. Pin assignments for COM, NO, IN, V+, and GND match exactly in the 14-pin SO package, allowing direct substitution without PCB modification-provided voltage and timing requirements align with the HC family's limitations.
What is the maximum on-resistance of MAX4066CSD+ at 3V supply?
The maximum on-resistance of MAX4066CSD+ at V+ = 3V is 170Ω, as guaranteed in the Electrical Characteristics table under "Single +3V Supply". This value is measured with ICOM = −1.0mA and VNO = 1.5V, and represents the worst-case RON across temperature and process variation for the MAX4066 variant (not the MAX4066A).
How does MAX4066CSD+ handle ESD protection?
MAX4066CSD+ provides on-chip ESD protection exceeding 2000V per Human Body Model (HBM) Method 3015.7. This level is verified during production testing and ensures robustness during board assembly and field handling. No external ESD components are required for typical industrial environments, though system-level protection remains recommended for harsh conditions.
